App

Company Reference: 

The Spa Boy is a self-monitoring, self-adjusting water care system designed for hot tubs. The system uses saltwater sanitizer generation controlled by sensors to provide an automated method of maintaining spa water conditions. Live energy usage monitoring, equipment operating status and water chemistry data are instantly transmitted to the spa control center. The results are displayed on the spa topside display, the smartphone app or a Web portal for analysis, adjustment and remote troubleshooting.

Total Coliform Test Indicates Presence of E. Coli

Publication Date: 
October 23, 2015

The Coliform/E. coli Indicator bacteria test kit (Code 4-3616-UV) includes five tubes, each with a nutrient tablet. The five tubes are each inoculated with 10 mL of sample water and incubated for 24 to 48 hours, depending on the ambient temperature. A change in the color due to acid production and the formation of gas bubbles in the reconstituted gel indicates the presence of coliforms.

Water Testing Kits

Company Reference: 

The Smart Brew Kit and Smart Brew Advanced Kit are handheld smart photometer systems for measuring a craft brewer’s water quality. Using the eXact iDip Smart Photometer System, the kits integrate two-way wireless communication with a smartphone. The kits measure calcium and magnesium hardness, chloride, pH, sodium, sulfate, total alkalinity and total hardness. The Advanced Kit includes the VisionPlus digital pH meter. 

Biopolymer Test Kit

Company Reference: 

This biopolymer test kit is designed to be used on site and provides real-time, accurate results in minutes. Every minute counts in sensitive storm water runoff situations, and waiting for results could lead to detrimental environmental impact at a job site. The new test kit is economical ($4 per test) and includes materials for up to 100 field tests. 

Portable Meters

Company Reference: 

This new family of portable meters is designed to measure pH, ORP, ion concentration with an ISE, conductivity and dissolved oxygen. The new meters—HI98190, HI98191, HI98192 and HI98193—feature a large backlit graphic LCD that is easily viewed under any lighting condition. An intuitive interface allows for a simplified user experience. All meters have dedicated keys for routine functions including calibration, setup, GLP and recall of logged data, which can be transferred to a PC with the built-in micro USB. 

Chlorine Sensor

Company Reference: 

FCL Series sensors use amperometric measurement technology to provide accurate monitoring of free chlorine in process applications. The sensors are compliant with U.S. EPA method 334.0 for measuring drinking water. Models are available to cover 0- to 2-ppm, 0- to 5-ppm and 0- to 10-ppm ranges. The sensors’ membrane design features a mesh reinforcement clamp for stability and durability. The integral 4-20 mA isolated signal output is enhanced to eliminate ground loop errors, reduce noise and block high-voltage transient surges.
